Hi and thnks for your inputand help
My sons pc :
amd xp 2000
ati gforce 4 mx440
when starting pc everything works fine until last sequence when pc boots user names.
That doesnt hapen screen goes black and stays like that.
When i restart and go to last good configuration nothing hapens same thing occures.
I can start only in safe mode.
I run adaware and spybot in safe mode.Same thing happens.
I have changed video card -same result.
Didnt try lot of things cos have few pc in the house and he doesnt depend on it but i tought to post so get few suggestions before i resolve it.
Didnt go to far with system restore.
My next move is to do sfc /scannow and see if that solved problem.
What would you suggest if that doesnt work?
Pc was working and boting normaly.I think he may done something with downloading games orplaying but dont think so as i set him up as limited user.
